External quest and map editor

I've decided the quest and map editor would be better as a separate WinForms project rather than being built into the game itself for now at least.

The reason I wanted to avoid this was because I'd have to replicate code, including large enumerations and data structures. Fortunately I've been able to find a way around Unity's tendency of re-creating the entire c# solution by project-linking files and breaking out enumerations.

Best of Both Worlds pt 1 & 2 I think.
